Longitudinal in vivo MRI atlas-based segmentation of T2-weighted images.
Top panel shows segmented ROI masks in the axial and coronal plane ([1] caudate-putamen; [2] cortex; [3] cerebellum; [4] thalamus; [5] globus pallidum; [6] hippocampus; [7] ventricles) overlaid on a T2-weighted image from a 20-month old wild-type mouse. Absolute volumes presented as means ± SEM.
